They have been added in v2.6.29 Could you add this information coming from the kernel commit adding them: o Freeze the filesystem int ioctl(int fd, int FIFREEZE, arg) fd: The file descriptor of the mountpoint FIFREEZE: request code for the freeze arg: Ignored Return value: 0 if the operation succeeds. Otherwise, -1 o Unfreeze the filesystem int ioctl(int fd, int FITHAW, arg) fd: The file descriptor of the mountpoint FITHAW: request code for unfreeze arg: Ignored Return value: 0 if the operation succeeds. Otherwise, -1 Error number: If the filesystem has already been unfrozen, errno is set to EINVAL. > Reviewed-by: Laurent Vivier <laurent@vivier.eu> > Signed-off-by: Aleksandar Markovic <amarkovic@wavecomp.com> > --- > linux-user/ioctls.h | 6 ++++++ > linux-user/syscall_defs.h | 4 ++++ > 2 files changed, 10 insertions(+) > > diff --git a/linux-user/ioctls.h b/linux-user/ioctls.h > index 944fbeb..adc07ad 100644 > --- a/linux-user/ioctls.h > +++ b/linux-user/ioctls.h > @@ -152,6 +152,12 @@ > #ifdef FIBMAP > IOCTL(FIBMAP, IOC_W | IOC_R, MK_PTR(TYPE_LONG)) > #endif > +#ifdef FIFREEZE > + IOCTL(FIFREEZE, IOC_W | IOC_R, TYPE_INT) > +#endif > +#ifdef FITHAW > + IOCTL(FITHAW, IOC_W | IOC_R, TYPE_INT) > +#endif > #ifdef FITRIM > IOCTL(FITRIM, IOC_W | IOC_R, MK_PTR(MK_STRUCT(STRUCT_fstrim_range))) > #endif > diff --git a/linux-user/syscall_defs.h b/linux-user/syscall_defs.h > index 8761841..ae4c048 100644 > --- a/linux-user/syscall_defs.h > +++ b/linux-user/syscall_defs.h > @@ -950,7 +950,11 @@ struct target_rtc_pll_info { > #define TARGET_FIBMAP TARGET_IO(0x00,1) /* bmap access */ > #define TARGET_FIGETBSZ TARGET_IO(0x00,2) /* get the block size used for bmap */ > > +#define TARGET_FIFREEZE TARGET_IOWR('X', 119, int) /* Freeze */ > +#define TARGET_FITHAW TARGET_IOWR('X', 120, int) /* Thaw */ > +#ifdef FITRIM > #define TARGET_FITRIM TARGET_IOWR('X', 121, struct fstrim_range) > +#endif move "#ifdef FITRIM" to previous patch. > #define TARGET_FICLONE TARGET_IOW(0x94, 9, int) > #define TARGET_FICLONERANGE TARGET_IOW(0x94, 13, struct file_clone_range) > >
